WBC: Total & Differential Counts

This test measures the absolute and relative counts of different types of white blood cells, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils. These counts provide valuable information about the functioning of your immune system.

This test is done for several reasons, including:

• To diagnose and monitor infections, allergies, autoimmune disorders, and blood disorders
• To assess the effectiveness of treatment for certain conditions
• To evaluate the body's response to chemotherapy or radiation therapy
• To investigate unexplained symptoms such as fever, fatigue, or recurrent infections

Your doctor may recommend this test if you have:

• Signs or symptoms of an infection or inflammation such as fever, chills, or swollen lymph nodes
• Suspected autoimmune disorders or blood disorders
• Been exposed to chemicals or substances known to affect blood cell counts
• Undergoing chemotherapy or radiation therapy

The normal range for total white blood cell count is typically between 4,000 to 11,000 per microliter of blood. Abnormal results could indicate various conditions such as infection, inflammation, leukemia, allergies, or certain medications. However, abnormal results should be interpreted by your doctor in conjunction with your medical history, symptoms, and other diagnostic tests.

• A small sample of your blood will be drawn from a vein in your arm.
• The sample will be sent to the laboratory for analysis.
• The analysis will be performed using an automated cell counter to determine the absolute and relative counts of different types of white blood cells.

• No fasting or special dietary restrictions are necessary.
• Inform your doctor about any medications or supplements you are taking, as some may affect the results.
• Wear loose-fitting clothing that allows easy access to your arm for blood collection.
• Follow any specific instructions given by your doctor regarding medication adjustments or other preparations.

• C-reactive protein (CRP): To measure inflammation levels in the body
• Erythrocyte Sedimentation Rate (ESR): To assess the presence of inflammation or infection
• Blood Cultures: To detect the presence of bacteria in the blood
• Bone Marrow Aspiration and Biopsy: To further investigate abnormalities in the blood cells

Leukemia is a cancer of the blood cells, particularly affecting the white blood cells. It leads to abnormal production and functioning of white blood cells, compromising the body's immune system and overall health. Leukemia can be classified into different types based on the specific cells affected and the rate of progression.
